No Neutral Smart Wall-Switch with LinkSwitch-TN2

This new video by Power Integrations illustrates a Bluetooth® Low Energy (LE) wall switch compatible with no-neutral wiring. The design is based on Power Integrations’ LinkSwitch™-TN2 offline switcher ICs which incorporate a 725 V rated power MOSFET and have a quiescent consumption of less than 75 µA.
